Safety check before expanding globs?

Safety check before expanding globs?

[Richard Hartmann]

Hi all,

I regularly use

 quux /foo/bar/*<tab>

to expand all files, do some modifications and then hit enter. Is
there any way to have zsh ask for confirmation (or require two tabs)
before expanding said list? Alternatively, is there a way to undo the
expansion?


Thanks,
Richard

Just wondering… why would you hit “tab” if it's not for expansion?

Yes, the “undo” function can do that. It's bound to ctrl+_ by default,
with emacs-like key bindings.

You might like the list-expand binding. Contrary to the name it
doesn't expand anything, it just lists the result of a glob below the
prompt.

The `_expand' completer is quite useful too. See "man zshcompsys" on
that function for details.
